1. Draw the mirror image of the molecule shown in the figure above 2. Change the configuration of carbon #1 by exchanging the position of bromine and hydrogen atom then write the mirror image of the molecule 3. Identify the configuration of carbon #1 and #2 in all of the stereoisomers. 4. Label the stereoisomers (Example: A, B, C, D, E, F ....) and identify the relationship of each pair of stereoisomers.
5. Construct models of all the stereoisomers of 1-bromopropene. Draw the line structure of your models. Are these molecules isomers? If they are isomers to what specific category do they belong? Assign E or Z descriptors to each compound, if appropriate. 6. Construct a model of dibromochloromethane and draw the perspective structure. How many planes of symmetry does this molecule possess? Construct the mirror image of your model. Are the two models superimposable? Classify or describe the relationship between these two mirror images, and assign R or S descriptors, if appropriate.
